Answer:

20 + 35x

Step-by-step explanation:

We have the expression 5(4 + 7x) and are asked to distrbute it.

When distributing, it's very simple, all you have to do is multiply the number outside the parenthesis with the numbers inside the parenthesis.

Therefore :

(5(4) + 5(7x))

20 + 35x

Answer:

LEAST DIFFICULT: B

MOST DIFFICULT: I

Step-by-step explanation:

LEAST DIFFICULT:

The easiest systems of equations to solve are ones in which x or y is equal to just a number , because in this case, you can just sub in that number in the other equations. Though not the only one, B is an example of this.

MOST DIFFICULT:

More difficult systems of equations to solve are the ones with different amounts of x and y as it requires more computation. Set I is an example of this

The Y is the diameter <br><br>Find Y <br><br>Area of the circle ​
yarga [219]

Answer:

<h2>Y = 22.56 cm </h2>

Step-by-step explanation:

To find the diameter Y of the circle we must first find the radius of the circle

Area of a circle = πr²

where

r is the radius

From the question

Area = 400cm²

Substitute the value into the above formula and solve for the radius

That's

400 = πr²

Divide both sides by π

We have

{r}^{2}  =  \frac{400}{\pi}

Find the square root of both sides

r =  \sqrt{  \frac{400}{\pi}  }

radius = 11.28 cm

Since we have the radius we can use it to find the diameter Y using the formula

diameter = radius × 2

radius = 11.28

Y = 11. 28 × 2

We have the final answer as

<h3>Y = 22.56 cm</h3>

Hope this helps you

if you travel to Jupiter, your weight would be 236.4% of your earth weight.How much would neil armstrong's space suit weigh on J
Margarita [4]
So,

This is simple multiplication once you've converted the percentage to a decimal.
236.4% = 2.364

Multiply 2.364 by 180.
2.364 * 180 = 425.52 lbs.

Neil Armstrong's space suit would weigh 425.52 lbs. on Jupiter.
